How long can I leave my industrial piercing out for before it starts to close?

I'm having a surgery tomorrow and I can't have my industrial in during it and also after the surgery around my face will be wrapped with bandages so I wouldn't be able to put it back in for a few days. I got the piercing around two and a half years ago so it is healed and I have taken it out for hours at a time before but never days. Will my piercing still be good after a few days or will I probably have to re-pierce it?
